Pantagruel's 1st Indoor Durban Poison

[Mike Wright]

I think for the next one I will use a 150 w hps. I think that will be enough for one plant without having to get into extra cooling.

Looking very frosty Panta, good work brother.

 

[Mike Wright]

Thanks! Hey, do you guys think I could run a 250 w hps in a big room without dedicated cooling, just the circulation fan and filter? I'm sure a 150 would be ok, but more is more...

i use a 600 watt in a grow tent with only a couple of oscillating fans blowing in through the lower vents causing the heat to escape out the top. With the window open in the room temps stay around 26 degrees C in winter.

Causes temp problems in the summer though so I only veg then.

With a bit of fore thought you would be perfectly fine with that set up, however, you can never have too much ventilation

 

[Mike Wright]

No kidding. Wow. I guess watts are watts, so if I'm using 450 now them I should get a similar amount of heat if I keep the total watts the same. I was planning to get a 250 and use a few cfls but maybe I should go straight to the 400. LA certainly makes good use of a 400 on his single plant!

 

[Mike Wright]

I can pick up a sun system hps 250 today. I kind of want to finish the whole thing cfl, but I would also like to maximize the yield.

Would the hps make a big difference for the last 4 weeks?

 

[Light Addict]

Yes my friend it really would, MJ puts most of her bulk on in the last few weeks and the improvement your gonna get will be quite significant with increased lumens and light penetration.

 

[Mono]

Like LA said, the hps will make a massive difference in the final 4 weeks of harvest.

Just make sure you keep everything else running smooth, the right amount of nutes etc and you will reap the reward.

 

[Mike Wright]

Ok! Got the light. Now to hook things up....

 

[Mike Wright]

Hmmm. It doesn't "look" particularly bright. Should you be able to stare right at the bulb? Maybe I have a defective bulb?

Ed. Should I be able to touch a 250 watt bulb?

 

[Light Addict]

You would leave your skin or melt it on your hand, if you touch an hps bulb when on. I glansed one once and damn it cooks ya instanly. Sounds like you have a fault!

 

[Mike Wright]

Ya. 2 hours wasted.

 

[Mono]

Ya. 2 hours wasted.

Did you wipe the bulb before set up? Any grease, dust, sweat etc will reduce it's output.

Also, HPS has to warm up so to speak, it will start off looking blue/white then turn bright orange. Although this should only take a couple of minutes at most.

Not too sure about a 250 watt, but like LA said hps should get hot. My 600 watt hps is too hot 3-4 inches away, I would hate to think about touching it...

 

[Mike Wright]

Bad Ballast. Got a 400 watt now. Let the good times grow!!

 

[Light Addict]

Welcome to the 400 club buddy! They be great little lights and you can still get really big weights off em!

 

[Mike Wright]

Hps

I like how the canopy looks under the new Sun System 400, much happier. I dispensed with all the cfls; I feel that I am getting more than enough all round coverage with the reflector.

 

[Light Addict]

Awesome my friend, its gonna make a massive difference to your finished weight and quality of weed!

 

[Mike Wright]

Well, the fungus gnats resurfaced, so I hit them with a dose of diatomaceous earth.

My clones were really sick, but a repotting and flush worked wonders and both are back on track, although I had to strip one right back to the stem.

 

[KingJohnC]

can you take some photographs of your new ballast, light and reflector?

 

[J189RFC]

Looking good Pantagruel! Good job jumping on those small problems right away!

King John Always the photophile I see!
